Health Economics - Essay Example The studies conducted by Shadick and colleagues focused on assessing the cost effectiveness of the vaccination against the Lyme disease by developing a decision analytic model. However, the evidence gathered for such an experiment may be not being considered as robust as it may seem because the probabilities and costs used by Shadick and Colleagues were taken from the literature which may not be considered as entirely satisfactory as it may seem. Further, best estimates were used on the base case analyses whereas the ranges used in sensitivity analysis were considered as clinically plausible only. Further, the evidence for compliance and risk effects were taken from relatively newer and recent trials which may not have considered as entirely satisfactory and untested due to lack of time tested empirical proofs. Further the evidence for cost effectiveness and management of Lyme disease were taken from one study only and the dollar values were updated up to 1998 only which may not entirely be considered as entirely accurate and relevant. Based on the above, it may be easily inferred that the evidence may not entirely be considered as robust as it lacks in many areas which were conceptually not corrected/designed according to the relevant economic variables. Any health state rated between zero and one can be rated as death or equivalent and perfect health whereas anything below zero on visual analogue scale may be termed as worse than death therefore based on three given states of A, B, C at 0.1, 0.45, 0.8, we can assign a utility of death or equivalent because all the utilities are greater than zero but less than one. Therefore, the utility assigned to all three states are effectively representing one state because all three are less than one and greater than zero. Q#1(d) An incremental cost effectiveness ratio (ICER) can be less than $40,000/- per quality adjusted year only if the persistence of vaccination efficacy is considered at three years. The traditional studies suggested that the cost effectiveness ratio, under two year time horizon of vaccination efficacy, the overall cost reach to $105,000/QALY. However, when this time horizon is stretched to three years, the incremental cost effectiveness ratio can reach up to $29,600/QALY. It is also important to note that Shadick & Colleagues took a radically larger efficacy period as in comparison to traditionally used. Q#1(e) With the increase in the vaccination cost by 100% i.e. from $150 to $300, the overall cost saving/QALY would decrease and the program would have moved up into the league table indicating smaller cost savings from the vaccination. The cost saving however is taken in terms of the costs averted while using the given vaccination. Q#2 Shadick and Colleagues considered a decision analytic model as one of the valid tools for making economic evaluation. Decision analytic tool is used when the intention of the researcher is to make justifiable and defendable decisions. Since, economics always involves a relative degree of abstraction therefore it sometimes becomes critical that such model for economic valuation is used which can provide researchers considerable degree of comfort while defending assessments made. (Arsham, 1994). Making comparison with earlier studies provide a peer reviewed evidence which can help researchers to take on the research

Eight steps of decision making process in management Research Paper

Eight steps of decision making process in management - Research Paper Example Under this process, policy makers must identify the problem under consideration, and clearly state it out, in a sentence that describes the causes of the problem and its consequences. This process also involves an identification of what an organization wants to achieve in case the problem under consideration is eradicated. This stage needs a consensus amongst everybody involved within the decision making process. The second step is the identification of the criteria (Robbins and Coulter, 2012). This involves identifying the various requirement needed for purposes of solving the problem under consideration. Under this stage, policy maker identify what the solution to the problem must accomplish. For example, if an organization is making losses, then the solution that the organization seeks is on how to increase the profitability of the business organization. On this basis, the solutions to be identified are methods of increasing the profits of an organization. The criterion therefore is that the solution must have the capability of increasing the profitability of the business organization. The third step in the decision making process is allocating weights to the criteria identified (Robbins and Coulter, 2012). This involves setting up of goals for the purpose of achieving a desirable outcome. For example if the problem under consideration is loss making in an organization. Allocation of weights will involve; how or at what percentage a criterion identified can increase the profitability of an organization. At this stage, terms such as high profit, low profit, or even 100% profit can be used. The fourth step is the identification of the various alternatives to the solution. It is important to denote that there are various solutions to a problem identified. For example in our case above, if a company is making losses, the organization can come up with a variety of solutions. These solutions include reducing operational costs, injecting more capital into the organ ization, or even diversifying its business operations. Under this fourth stage, policy makers only identify the various solutions available for purposes of solving the problem under consideration. They do not carry out an analysis of the problems. The fifth stage involves analyzing the alternatives presented. This stage involves an analysis of the various alternative solution to the problem identified. The method to use in analyzing these alternatives will emanate from the criteria identified at the second stage (Lynch, 2012). For instance, in a loss making organization, the criteria of identifying a solution is based on how a method will increase the profitability of a business organization. On this note, policy makers will analyze the various alternative solutions to the problem. At this stage, policy makers must rank the various alternatives to the solution from the most effective, to the least effective. Under this stage, policy makers can analyze the alternatives by using eithe r qualitative or quantitative methods, or a combination of both. The intention here is to find the most effective solution to the problem identified. For example, the solutions identified to increase the profitability of a company are, reduction of operational costs, injecting capital into the organization, or even diversifying the operations of the business. Policy makers will analyze all these options, and grade them from the most eff

Slavery Before the Trans-Atlantic Slave Trade Essay Example for Free

Slavery Before the Trans-Atlantic Slave Trade Essay What is the difference between slavery prior to the 14th century with that of slavery after the 15th century? Slavery existed long before the original slaves came to America. In fact, slavery prior to the 14th century differed greatly from slavery after the 15th century. Slavery was essential to many economic and social structures. For example, ancient Greece and Rome had many slaves. They differed from the form of slavery after the 15th century, though, due to the background of their slaves. Slavery was not necessarily racial or ethnic in origin prior to 15th century slavery. It was often captured enemies of war from many different places. However, when the Trans-Atlantic trade began, the majority of the slaves were African. Another difference is that the Africans were treated as objects, whereas prior to the 14th century, they were not legally the same as objects. Another difference is the jobs that they occupied. For example, the majority of the Athenian slaves were domestic servants, but the majority of African Americans had brutal and tedious jobs such working in fields all day. Slaves were also used to enforce religions, such as Islam. The Ottoman Empire forcibly converted approximately one million non-Muslims. However, the main purpose of Africans in the Americas was primarily as a work force. A significant difference was that of the Aztec slavery. For them, slavery was not considered hereditary. Therefore, a slave’s child was free. After the 15th century, a slave’s child was still considered a slave: it was hereditary. Slave trade was different before the Trans-Atlantic Slave Trade began.

Gothic in Wuthering Heights and Dorian Gray

Gothic in Wuthering Heights and Dorian Gray The duplicity or sometimes called the Doppelganger is a common theme in gothic fiction works such as The Picture of Dorian Gray or Wuthering Heights. While in the first novel, this theme regards the division of the main characters into two different bodies, in the latter, the self is no longer divided into different embodiments, but it can be found in the same character having the same appearance while portraying one self or the other. In other words, Dorian Gray has a certain different figure when they display the other self, while Cathy and Heathcliff have an inner other self not an outer one and are completely unaware of its existence. While in The Picture of Dorian Gray, the depiction of self is related to realism and the depiction of other self relates to gothic representation, in Wuthering Heights, when talking about Catherine it is the other way around. The Picture of Dorian Gray tells the story of a young man who decides to make a Faustian bargain in order to gain and preserve eternal beauty. The novel can be interpreted as classic gothic horror fiction in which the reader can easily spot the Narcissus myth and the theme of duplicity which presents Dorians two selves: the public one constructed in a realist way and the private one, constructed with gothic means. On the other hand, Wuthering Heights is a gothic novel in which the protagonists are, unlike other novels, anti-heroes. The main character, Heathcliff is a man whose desire of revenge destroys both himself and the other characters of the novel. He is depicted at first as a loving person but in the end as a violent revengeful man. The female protagonist, Catherine Earnshow is a woman who finds herself in crisis of identity. Both characters need to make a division in themselves in order to express their feelings for each other. The division in The Picture of Dorian Gray is made with the help of a portrait, an outer body which guests the other self of the main character, whereas in Wuthering Heights, there is no need for another body. Dorian Gray is presented in the first chapter as a young man of extraordinary personal beauty, unspoiled by sins and failure. The picture as it is presented in the first chapter reveals Dorians first and true image: he is young, handsome, and innocent, without stain. However, Dorian Gray will not remain this way throughout the novel. He will change and not in a positive way. This is where the author brings to light the duplicity theme. Similar to Dorian Gray, Heathcliff is depicted in the beginning of the novel as a positive character. Although he lacks Dorians looks, he is a boy, and then a man capable to love and give. The audience is assured that Heathcliff does love Catherine and the way in which the author describes the brutal treatments Hindley applies to him can cause the reader pity for Heathcliff. In the first chapters of the novel, before Heathcliff leaves Wuthering Heights, the entire atmosphere is one which abounds with gothic elements. The author presents here the first nature of Heathcliff, while entire passages describe the manor as a dark, bleak, unfriendly place. The main character can be interpreted as of pure gothic construction. He is a mysterious man whose past nobody knows, but on the other hand, he is presented as romantically involved with Catherine, thus as a positive character. Exactly like Heathcliff, Dorian from the end of the second chapter is no longer Dorian from the beginning. The reader faces in just a few pages Dorians transition. His naivety and his purity disappear when he realises the importance of his beauty and the fact that he will lose it someday. Henry Wotton manipulates his mind and turns him into a person ready to sell his soul in order to preserve his beauty. In the moment when he sees the portrait, he is as fascinated by himself as Basil is and acts as if this is the first time when he sees himself. This passage comes similar to the moment when Narcissus sees his reflection in the water for the first time and brings the idea of self-worship which will finally lead to self-destruction. Infatuated with himself, Dorian becomes a Machiavellian person, wanting to preserve the moment, no matter the costs. Dorian loses his innocence but, despite the fact that his soul is unceasingly deepening into the negative way of living, he is admired for his beauty and intelligence, for his talents. This leads him to plays with peoples minds hiding his true shape and making them believe that his appearances are similar to his inner self. This outer self, the one he displays in front of anyone is in total opposition to the self which he prefers to cover. On the other hand Heathcliff does not feel the need to cover his other self. There is a certain moment in the book when Heathcliff changes his attitude. Feeling abandoned, Heathcliff feels the desire for revenge which brings up the other self in Heathcliff. He becomes a violent person who seems incapable of good feelings and begins acting like a demonic character, destroying everybodys lives. His actions seem to be results of the distortion in his natural personality. Dorian changes too. Dorian loses his innocence but, despite the fact that his soul is unceasingly deepening into the negative way of living, he is admired for his beauty and intelligence, for his talents. This leads him to plays with peoples minds hiding his true shape and making them believe that his appearances are similar to his inner self. This outer self, the one he displays in front of anyone is in total opposition to the inner self which he prefers to cover. In order to construct the other self, Oscar Wilde refers to gothic imagery. He creates the key element, the picture and develops its image as the one of different character of the book. The first gothic element of the book is the Faustian theme. Dorian unconsciously sells his soul to the devil in order to obtain eternal youth and beauty. Henry Wotton plays the part of devils advocate, devils representative without even knowing it. He inspires Dorian to make the fatal wish: the paint should age instead of him. The fact that the portrait ages in Dorians stead cannot be logically explained, thus it is the supernatural element which lead to the development of the plot. From the very beginning presented as a fantastic element, the picture represents the embodiment of Dorians other self. His sins, his mistakes and his other nature are revealed on the canvas. Knowing that, Dorian wants to protect this image, wants to hide it and locks the portrait in the attic so as no one should see the im age of his soul. Although he is aware of the fact that his soul is dark and stained with sins, he continues to live as before because he thinks he can no longer be forgiven and his soul saved. The moments when Dorian is possessed by his other self, abound with gothic elements. So are the moments when Heathcliff becomes violent and the author presents his inner sense of revenge and hatred. In Wildes novel, the scene of the murder is presented in a dark atmosphere with the lamp casting shadows on the wall and the blowing wind. Moreover, Dorian kills Basil only after he looks at the portrait and seems to be captivated by something hiding beneath the canvas. Violence breaks through and he stabs the painter without any sense of remorse. The way in which he decides to make the body disappear is a result of his mad ego that seems to have no feelings and to be totally detached from the realist life. Science is here presented it its negative part. With science, Dorian finalises the murder, making the evidence disappear forever. His other soul has become a malicious and manipulative person. He confides in the book Henry gives him and takes it for granted, as a way of living. It is a poisonous book, symbol of his degraded life. Moreover, the gothic atmosphere appears again when Dorian visits the opium den which is the reflection of Dorians state of mind. The den is a place of lost souls where Dorian finds comfort, he cures his soul by means of senses, because he suffers not only physical but also mental. Catherine, on the other hand does not change in a negative way. She is ashamed of her natural self and decides to make a step further, to change and to embrace another self in which she will finally feel uncomfortable. In childhood she is her true self, without carrying about her future as woman and as a wife. She has internal conflicts which intensify her psychological complexity. She suffers from a self-divided personality, regarding what she truly desires and what she thinks she should become as a woman. This is a point where one could speak of her id, what she desires, her instinctive impulses and her super-ego, what she thinks she should become as a woman, her moral ideas, and the expectations of the patriarchal society. After returning from Thrushcross Grange she is different because, not only does she act differently but she struggle to refrain from her usual behaviour. Nelly actually realises what has happened to Cathy and even says that she adopt(ed) a double character without exactly intending to deceive anyone. Catherines conversation with Nelly is the final evidence that she has a divided self. She tells her that she loves Heathcliff, that she is Heathcliff, suggesting that her real self is the one which complements Heathcliff, which makes her like him, turning them into the figure of an androgynous. She is able to refrain from her true self until Heathcliffs returning. Now she suffers again from an identity crisis. She looks in the mirror and says that the image is not hers, it is in fact the reflection of the part she had to play in order to be a respected woman, to fit in the bed of Procrustes the society showed her. Once Heathcliff is back, she is unable to live in this way anymore and thi s destroys her. There is the interpretation which says that Heathcliff, being Catherines matching person, actually is her doppelganger, her dark hide, which she wants to hide, exactly like Dorian Gray. This is suggested several times when the main characters say that the other is part of their lives, oh themselves à ¢Ã¢â€š ¬Ã… ¾I cannot live without my life! Cannot live without my soul!; à ¢Ã¢â€š ¬Ã… ¾I am Heathcliff. The ways in which the protagonists are firstly presented is a romantic one with characters relating to nature who rebel against the world they live in. The gothic atmosphere is intensified by supernatural elements and melodrama. But Bronte created two different places where Catherine leaves, suggesting her split personality. The first one, the Wuthering Heights identifies with her true self and it is presented with gothic constructions such as the description of the moors, the manor, the atmosphere, the, wind, the storm or the rain. On the other hand, Thrushcross Grange is depicted in a positive manner, in a realist way, with all the elements of the common life representing Catherines other self. There is a striking difference between these two as it is between Catherines sides. The realist depictions in Wuthering Heights are somehow related to the other part of the novel, starting with the first scene where the reader encounters Young Cathy. Her and Haretons story is depicted in a realistic way, especially because of the happy ending. In the second case, the realism of the novel is depicted from Wildes representation of the Victorian world. Dorian is after all, an aristocrat living in a rich world where dines and opera are something common. His first self, the one everyone knows, the one Basil has painted at the beginning of the novel is the one living in this world. He is a rich art connoisseur; he likes parties and luncheons and attends theatre and opera. The Victorian society presented in the novel is one where people live from undeserved inheritance and enjoy gossiping and judging the world around. Dorian lives a secret life within an apparently respectable society. While a beautiful forever-young man in his public life, Dorian is presented as a debauched, violent person. The atmosphere in the next chapter is completely different from the one in the previous. The life at the countryside seems idyllic but Dorian is uncomfortable here because he feels he is stalked by James Vane. James presence is like a ghost haunting Dorian throughout the novel, being the embodiment of Dorians conscience. In the other book, the main character is not haunted by feelings or remorse, but by Catherines ghost who has not find peace. This idea brings another gothic element to both stories. In both novels, the theme of the divided self dominates the entire atmosphere, but in The Picture of Dorian Gray is easier to observe. However, the three characters that experience this kind of mental or physical division are presented as tormented souls, unable to find their rest.

Comanche People :: essays papers

Comanche People In the western part of Oklahoma, ranging south on the Plains, a courageous people, known as the Comanches, roamed. They were a nomadic people who lived in skin teepees, which were easily moved from place to place. They had strong friends among Indians, such as the Kiowas and Apaches, as well as many enemies. This is only a minute view into the Comanche tribe, however. Before learning about the tribe's history, one must learn first, who the Comanche people were, and then who they are now. Where did the name Comanche originate? What are characteristics of these people? How is the tribal system organized? These are questions that must be answered in order to learn more about the tribe. In order to fully comprehend their past, one must look to their background and then to their present history. So, put on your anthropological hat, and explore the lives of the Comanche. It has been said that the origin of the name Comanche is a contradiction of the Spanish tern camion ancho, meaning literally, the broad trail. This term refers to the broad range traveled by the warriors of this tribe on their trading and war expeditions. First applied to the tribe soon after 1700, the name Comanche is spelled mjany different ways, such as Camanche, Commanche, or Cumanche. The Comanche Indians call themselves Nerm, meaning, people of people. The Comanche are from the Shoshonean linguistic family. This linguistic family developed in the Shoshoni and Snake River regions of Wyoming and Idaho. The linguistic stock is also said to have been of Nahuatl origin in Mexico and remotely related to the Aztec. They are the only division of the Shoshonean family who left their haunts in the Rock Mountains and established themselves on the Plains as one of the great tribes of the region. They later became divided in as many as twelve different bands. The most prominent band in the history of Oklahoma are the Penateka, meaning honey eaters, and the Quahadi, meaning antelopes. In Oklahoma, as early as 1869, the total population of Comanche was estimated at 2,538. During other periods the Comanche numbered 1,399 is 1880, 1,553 in 1898, 1,476 in 1910, 1,718 is 1924, and 2,700 is 1950. Texas, on the other hand, reported that in 1851, the Comanche population totaled 20,000.
